NOTES:
• Current JOUST games use green-label ROMs. Earlier games have either yellow or red-label ROMs, which are
interchangeable and may be mixed in the same game. DO NOT attempt to mix green-label ROMs with red or yellowlabel ROMs.
• Boards with green-label ROMs should include jumpers W1 and W3 only. Boards with red or yellow-label ROMs
substitute jumpers W2 and W4.

POWER TURN-ON
CAUTION - This game must be plugged into a properly grounded outlet to prevent shock hazard and to ensure proper
game operation. DO NOT use a "cheater" plug to defeat the ground pin on the line cord, and DO NOT cut off the ground
pin.
WHEN THE GAME IS FIRST TURNED ON it produces a sound. Simultaneously general illumination should come on
and a moment later a scanning “rug pattern”' indicating the RAM test should appear on the screen. Next the rug should
become stationary as the ROM test is performed. In a correctly running game the rug pattern will be followed by the
message "INITIAL CHECKS INDICATE ALL SYSTEMS GO". If RAM or ROM failure messages come up on the screen
instead, refer to Power-Up Tests in TROUBLESHOOTING PROCEDURES.
GAME OPERATION
GAME START - Insert coins; a random sound is produced and credits are displayed on the CRT. With two or more credits
displayed, pressing 2-player start initiates a 2-player game where each player gets five* mounts (turns).

PLAYER CONTROLS
The Joystick sends the gladiator and his ever stalwart mount (ostrich or stork) boldly to the left or to the right.
The Flap Button causes the hero’s mount to spread its robust wings.
GAME PLAY
AT SOME FAR-DISTANT TIME two fantastic gladiators meet and square off for battle. Each is mounted on a fanciful
bird of prey (ostrich or stork) who’s wings can carry it from the cliftops to the mouth of the abyss and hopefully back . . . or
the bubbling lava below will increase it’s toll.
While your mount is a skilled flyer, your opponent is a shrewd gladiator. You must prove you are his better. Stealthily you
must pilot your mount above him, and cleverly you must stalk him . . . to strike at the moment he least suspects you! And
always remember this rule: In every Joust, the highest lance wins!
Of course your opponent will resist your attempts, all the while pursuing his own designs on you. Each gladiator has five*
mounts. Every time you’re toppled you must mount a new bird for the next joust. The gladiator who scores the most
dismountings is the winner.
YOUR PATH MAY SEEM CLEAR and your work cut out, but just them a flock of vicious Buzzard-Riders will ambush
you! Ruthless even as they are dismounted, these wily Buzzard-Riders instantly lay their eggs. You must pick up the eggs
or they will soon hatch into even more persistent and antagonistic foes!
Fortunately at 20,000* points (should you make the grade) you will be awarded another bird to mount against the loyal
opposition.
Joust is designed for either one or two players.
HIGH SCORE SIGNATURE
Select letters with the joystick. Push right to move forward through the alphabet; push left to move backward. Then push
the FLAP button to lock in the letter.
BOOKKEEPING AND EVALUATION TOTALS
1. In Game-Over Mode, open the cashbox and depress the cashbox advance switch. The advance switch located on the
coin door can also be used. The CRT should indicate all bookkeeping and evaluation totals. If so, go to step 3. If
the CRT display comes up in the ROM test, perform step 2.

2. Continue to depress the cashbox advance switch, stepping the game through test programs for ROMs, RAMs, CMOS
RAMs, color RAMs, sounds, switches, and then CRT test patterns, of which there are five. The fifth test pattern,
color bars, directly precedes the CRT display of the bookkeeping and evaluation totals.
